Yeah, you can tell from the title I live on the topside of the world. A bit egocentric for sure but the winter is setting in here and it’s looking cold. Anthony Watts did a post on PDO (Pacific Decadal Oscillation) which has recently shifted colder. A lesser known form of la nina the PDO is yet another regular oscillation in the weather system. One which doesn’t get the press it deserves simply due to its longer timescale.

The blue wedge region surrounded by the green is apparently the typical signature of the PDO cold cycle. What didn’t get enough attention IMO is the trend. By the trend we should have been expecting this event for some time. Fortunately for us, digital diatribes (link on right) kept up with the trend and laid it out several days before the main stream media and Watts Up picked it up. Take a close look at this graph.
